Help [Resources request] - Learn to edit L2 client files

[MiniShop]

Hello all,
 

Developer for over 10 years but only lately I've started to fiddle with L2 client files, I'm a complete noob at this.

Are there any resources I can have to learn how to decompile and re-compile the files that ship with the game?

I have a ton of compilers and decrypters but can't make sense of how to use them and for what scenarios.

 

Understanding the files' structure an what they are doing would be a great start.

If you have any links/documents to share would be great!

 

Thanks in advance

Any source of learning would be highly appreciated if any of you folks are willing to share.

Which files were you looking to decompile exactly?

I first would like to understand how things are tied together so I can later on modify the UI to help me gain more info from the game.

A simple example (simple in my mind at least) of what I'd like to do is to display buffs canceled/removed for a brief period of time, or to have some kind of indicator of how much time is left of zealot a GK or Titan has. Things like that which I believe require an overall understanding of how the files work and what and where should be modified.

So far I've managed to:

- Update Interface.xdat (XdatEditor)
- Find out that for Interface.u you need a decompiler and a decrypter/encrypter (WOTgrealExporter)
For this one, I get an error when I try to extract the.uc files

- Make use of UnrealEngine2Runtime  to check some classes, but that's all I managed to do with it, I don't really understand its overall use

- L2 File Editor EN by Miko v2 - I managed to open some files but for some of that same type it did not work (Skillgrp.dat)

 

That's where I am so far. Bits and pieces that I managed somehow to tie together but I still don't see the full picture.
